These bearings sit inside the engine block and they’re what the crankshaft actually spins on. Think of it like the crankshaft is a rotating shaft and these bearings are the supports that keep it from just banging around and wearing out the block itself. They allow that shaft to rotate smoothly with minimal friction. A set includes all the bearings along the length of the crankshaft – usually a handful of them. They’re absolutely critical to the bottom end of the engine. They take a lot of stress. Everything from the force of the pistons going up and down to the overall rotational force of the engine is transferred through these bearings. They convert that pushing motion into rotational motion, which, naturally, drives the vehicle. They act like a shield between the incredibly heavy rotating crankshaft and the engine block. Well, these bearings do wear out over time. Oil keeps them lubricated, but eventually things get a little tired. You’ll notice if they start to go bad usually by an engine knocking sound, especially under load. That’s the sound of the crankshaft starting to hit the worn bearing surfaces. If you ignore it, things get worse quickly, potentially leading to catastrophic engine failure. Replacing them is a pretty involved job, because you have to get into the bottom end of the engine, but it’s way cheaper than replacing the whole engine. You can find a good Main Bearing Set VAG over at Fixparts Online if you're looking for a reliable kit, and they’ll have all the bearings you need for a complete job. Ignoring worn bearings is a risk you really don’t want to take, it’s a fundamental part of what keeps your engine running.
